Abstract
Objective: The purposes of this study were to establish cephalometric norms of Mongolian adults, which have not previously been reported in orthodontic journals, and to compare them with cephalometric norms of Korean adults. Methods: Lateral cephalometric radiographs of 74 Mongolian adults (35 men, 39 women) and 95 Korean adults (52 men, 43 women) with normal occlusions and well-balanced lateral profiles were obtained. The subjects were chosen by orthodontists of the same ethnic background. Forty craniofacial variables were measured, and groups were compared by analysis of covariance. Results: The cephalometric norms for male and female Mongolian and Korean adults with normal occlusions and well-balanced lateral profiles were established. Sexual dimorphism was found in linear skeletal measurements and vertical skeletal relationships. Compared with Korean adults, Mongolian adults had shorter anterior facial height, more prominent chins, and more upright upper incisors. There were few differences in soft tissue measurements. The differences were statistically significant, but their clinical importance may be limited. Conclusions: Cephalometric differences can be considered, but little difference may exist in the orthodontic diagnosis and treatment planning of Mongolian and Korean adults.
